Using South Dakota SOS Enterprise business and UCC services

Business information search and UCC services both run on sosenterprise.sd.gov under separate Business Services and UCC paths. Use Business Information Search for entities and IDs; use the UCC services page for financing statement tools, subscriber access, and certified search requests the division describes. Same host does not mean one screen replaces the other.

SOS information

South Dakota business entities & Secretary of State workflows

Search business entities

Search by business name with starts-with or contains matching, or by Secretary of State Business ID. Limit to active entities when that filter fits your task. Results can be viewed and printed from the detail screen; bulk entity downloads are a separate paid product linked from the official site when you need the full database.

Business search does not open the UCC filing and lien tools; use the UCC services path when you need financing statements.

File or manage business registrations

Log in through SOS Enterprise when the workflow requires it for filings tied to an existing business record. Follow current fees and forms linked from sdsos.gov before you mail or pay online.

UCC information

Financing statements & lien search

UCC services

The UCC default page shows how current the office’s processed filings are, links to online UCC1/UCC3 style generators (often print-and-mail unless you are a subscriber), the UCC2 certified search and copy request PDF, and database download requests. Pre-paid PAD account holders use the login area for subscriber-only filing and search; do not use that block without an account. Match names to how parties filed and read fee and mailing instructions on the live page.

Tips if the site feels confusing

Business Services and UCC are different menus on sosenterprise.sd.gov; a clean entity record does not prove you searched UCC records.
Subscriber PAD login is only for pre-paid accounts; public users should follow the print-and-mail or PDF request paths the division publishes.
Official fees, certified search rules, and forms belong to the South Dakota Secretary of State and your advisors, not third-party summaries.

Starting a business in South Dakota

Entity search on this page helps you verify names and good standing. When you are ready to form a new LLC, corporation, or nonprofit, use the same next steps we link from Business Lookup: confirm the name on the official register, choose a structure with your CPA or attorney if needed, then file through the state agency (and plan for publication, registered agent, and any industry licenses that apply).

Typical state filing fees

These amounts can change when agencies update their fee schedules. Double-check the current fee list, forms, and deadlines on the official South Dakota business filing site yourself before you pay or submit anything.
